Unity

Unity is a power exclusive to Commander Shepard, and can be used by any class. Unity revives any downed squad members, and this requires you to collect Medi-Gel. For each squad member revived, one unit of medi-gel is used. Note that using Unity with neither squad member downed will not use any medi-gel, nor will it affect anything else. It is likely that you will be able to upgrade this power.
